Pussy Is The Gross National Product Of Brazil
That is just one of the priceless pearls of wisdom that self-professed "Game Advisor" Tariq Nasheed provides in his mack-centric travelogue of Rio de Janeiro, Brazil. Anthony Bourdain aint got shit on Tariq!





I need to start socking away my pennies to save up for a trip to Rio and grab me a "How to Speak Portuguese"  book from Borders.

Livin’ On the Edge:
Variance in Mammalian Species Richness and Abundance
Between Eucalyptus and Pasture Edges of the Atlantic Forest

Introduction

The Atlantic Forest is one of the most unique environments on the planet—providing hundreds of priceless resources for human beings around the world—but after decades of degradation, pollution, and exploitation, only 7-8% of the original Mata Atlântica ecosystem remains (Galindo-Leal and Câmara 2003). Unfortunately, this small percentage is still threatened by unsustainable human practices and a lack of adequate preservation efforts. One of the most imminent issues jeopardizing the survival of these existing forest remnants is fragmentation, which isolates populations, curtails biodiversity, and exacerbates extinction risks (Chiarello 1999). A vital step in understanding and eliminating the consequences of fragmentation is determining species diversity at the forest edges, and measuring how this diversity varies across different edge types, in order to improve conservation techniques, develop more efficient management strategies, and advance policies regarding forest preservation (Marsden et al. 2001).

In my project, “Variance in mammalian species richness and abundance between eucalyptus and pasture edges of the Atlantic Forest,” I will attempt to evaluate both species richness (number of species) and abundance (number of individuals) at eucalyptus and pasture edges of the Atlantic Forest using baited sand traps to collect mammalian tracks. The results of this project will also be applicable when assessing the Green Hug concept, an important measure being taken to diversify forest edges. Eucalyptus forests are planted at the edge of the Atlantic Forest, in order to create a buffer between the forest and surrounding pastures and human inhabited areas. Theoretically, the presence of this buffer should indicate elevated species presence at this edge because the eucalyptus forest “hugs” the Atlantic Forest and mitigates the division between the two environs (Ferinmore and Cullen 2002).

The neighboring habitats that surround the forest fragment edges—such as eucalyptus stands and pastures—are known as matrixes (Gascon et al. 2000). These buffers are critical for the survival of the forest fragments that they converge with; the harshness of a matrix (how closely the matrix resembles the ecosystem it encircles) can determine whether or not it provides crucial protection for the forest interior because it limits the harmful outside factors—such as pollution—that infiltrate the forest (Umetsu and Pardini 2007). In my project, the forest edges and their corresponding matrixes are the areas that I’m concerned with—through my sand trap experiment, I will attempt to determine the difference between species diversity of edges adjacent to eucalyptus and pasture matrixes.

Question and Hypotheses

In this project, the main question I will be asking is: How does the richness and abundance of mammalian species at Atlantic Forest edges vary according to the presence of eucalyptus and pasture matrixes? Based on research regarding this topic and my own prior knowledge, I have formulated a hypothesis in answer to this question: There will be a difference in species diversity between eucalyptus and pasture edges; there will be more mammalian species richness and abundance present at eucalyptus edges than at pasture edges (Ha).

H0: Peucalyptus edge = Ppasture edge
Ha: Peucalyptus edge ≠ Ppasture edge

Methods

In order to obtain a more accurate measure of species richness and abundance at forest edges in the Mata Atlântica ecosystem, I have chosen three different sites in the Nazaré Paulista region of Brazil where I will lay my sand traps. Each of these selected sites is a forest fragment that has both a eucalyptus edge and a pasture edge, in an attempt to increase the statistical relevance of my results. At each site, I will lay six 50x50cm sand traps (three replicates at each edge) at randomly selected points along a 50m line, for a total of 18 traps. These traps will be baited with bacon and bananas, in order to attract mammals. In a study of Atlantic Forest matrix quality, Umetsu and Pardini (2007) analyze small mammal populations because they are the most diverse genre of mammals present in Neo-tropical regions. If my results are similar to those of previous sand trap projects completed by SEE-U students at IPÊ, most of the wild animal tracks in the traps will belong to small mammal species (Peterson 2006 and Mintz 2007).

After setting and baiting the traps, I will return early the following morning (to avoid disturbances and loss of data) to record the tracks; I will photograph each track and include a scale in each photo, in order to gauge size and aid in identification. In both previous SEE-U sand trap projects, students checked their traps 6-7 times. Neither of these students was able to disprove their null hypothesis (Peterson 2006 and Mintz 2007). I will check my traps a total of ten times; I would like to collect more information and possibly determine if these students were unable to disprove their null hypotheses because they did not gather sufficient data.

When analyzing the results of my experiment, I will use a two-tailed t-test to determine the difference in species diversity between the two matrix types. By including multiple replicates, selecting random trap sites, and checking the traps additional times, I hope to collect statistically viable data that will prove my hypothesis. In previous SEE-U sand trap experiments, students faced two main obstacles when laying their traps: steep inclines and a lack of forest clearings (Peterson 2006 and Mintz 2007). In order to avoid the first issue, I have chosen sites with as little incline as possible, although some was unavoidable. Regarding the latter issue, I may have to adapt the random selection of my trap locations if I am unable to place them in relatively clear areas. Another complication I anticipate is inclement weather, which may disrupt my sand traps (so I will check the traps as early in the day as possible).

A notable limiting factor of my project is the proximity of my sites; I cannot measure the general species diversity of the Atlantic Forest because all of my sites are located in the Bairro do Moinho, but I have chosen three different sites instead of using pseudo-replicates, which will hopefully expand my data and increase their pertinence regarding this specific location.

Loooong hours in the classroom
Today was not the most exciting, but I really can't complain--I am in paradise, after all. I woke up early and went for a run with Julia (my roommate) and Aylesse. We ran for about 40 minutes. I definitely feel better about my performance today; yesterday I could barely make it up the hills (there are many, many hills). Retrospectively, I've decided to attribute my violent wheezing and chest pains yesterday to the higher altitude. Otherwise I would have to acknowledge just how out of shape I have become. No thank you.

Today was lectures and exercises and more lectures. We had a quiz too, but I got a 9/10 so I'm pretty happy with that. I need to get an A in this course since it's 6 credits and will serve as a fairly solid boost to my GPA. I'm at a 3.6 right now and I need to hit 3.7+ by graduation so that I can qualify for a Marshall Scholarship and get my PhD for free in the United Kingdom. It's a lofty goal, but it would be an amazing opportunity. And who knows, it might happen.

We had a lesson today about ecological footprints, a subject I find very interesting. I did two calculations and determined that my footprint in New York is much smaller than in Maryland--no surprise there. (If anyone who knows me, or knows my shoe size, is reading this, I'm sure you're thinking about how big my footprint is anywhere. Har har.) Being a vegetarian really reduces my impact on the planet; being a vegan would reduce it even further. Definitely an option I would consider, but I'd have to give up ice cream. And yogurt. And cheese. That would be rough.

The food here has continued to exceed my expectations. I've been eating yogurt, granola, and bananas for breakfast, followed by lots of vegetables (squash, beets, potatoes, zucchini, etc.) and salads for dinner. Everything smothered in hot sauce, just how I like it. And I've been drinking lots of water, tea, and coffee. I hope the water is negating the dehydrating effects of the caffeine. The only issue is that since I've been eating so many meals per day (breakfast, coffee break, lunch, coffee and cake break, dinner), I haven't been able to measure how much I've been eating. Everything is healthy and incredibly unprocessed (a welcome change from my usual diet), but I just hope that I don't get fat(ter) while I'm here.

This evening we had individual discussions with our professor and TAs to discuss our project topics. I think I'm going to scrap the idea about dogs (I just can't think of a hypothesis or experiment) and study erosion control methods instead. I'm still in the planning stages, but I'll probably spend Friday hashing out the details.

I'd like to reflect more on what I learned today, but my mind is drawing a blank. This entry seems a little vacuous, so hopefully I'll actually be able to express some thoughts tomorrow. I might go to bed soon... Julia, Kaitlyn, and I watched half of Paris, Je T'aime last night (one of my *favorite* films), so we'll probably finish it after our reading is done. The nights here have been very laid back so far, but we're having our first "social" tomorrow night, so things are bound to get a little crazy. I hope.
 
 
   
 

Across the water and up a mountain
I finished my paper last night! What a relief. I guess this means that I'm officially a junior in college--pretty exciting. (Except I'm one step closer to joining the workforce and losing the allowance my parents give me...damn.) This paper definitely wasn't the best thing I've written this year (it might be the worst), but at least it's over with. My grades should come in soon; I think I did relatively well.

Today was another lovely day in paradise. I had planned on waking up early to go for a run with some of the other students, but I stayed up late writing so I decided to sleep in. After breakfast, Fernando--one of our TAs--gave a lecture about conservation biology and what goes on at IPE. He posed one question that I found particularly interesting: Why should we spend money to conserve species when there are millions of people around the world dying from starvation?

Well, our money isn't being spent on international aid to save impoverished peoples... it's being spent on this "war"! The total cost of the Iraq was is over $500 million so far: Imagine how many ecosystems could have been saved with those dollars that were used to destroy life rather than preserve it...

Fernando lectured for about an hour before we grabbed our backpacks (stocked with bug spray, windbreakers, and binoculars) and headed down the hill past the organic garden to two boats waiting on the shore. We hopped in and began our journey to Fazendinha, a resort further up the reservoir. The boat ride was absolutely lovely--I took some great pictures (I'll post them here as soon as I upload them from my camera). When we arrived at our destination, we were greeted by a few charming dogs--mostly lab mixes, but a couple of smaller breeds too. And none of them were neutered. I think I might study this topic for my individual project: Measure dog population sizes (and the population sizes of other domesticated animals); how neutering would change population numbers; what neutering services are currently available; how dogs and other domesticated animals affect the natural environment (ie. by spreading diseases); etc. Hopefully I'll be able to find some relevant research via Google.

We began our climb up a small mountain (a hill, really) soon after we docked and used the restrooms. The trek was definitely uphill, but it wound around the incline so it wasn't too strenuous. And it was absolutely breathtaking. We were surrounded by an incredibly lush canopy hung with thick twisted vines, interrupted by spatters of sunlight shining through breaks in the leaf cover. When we were about half way up, Juliana--another TA--asked us to find something interesting and show it to the rest of the group. I found several species of lichen on a tree: some green, some red, and some orange. I also noticed that on all of the surrounding trees, the lichen only covered one side because the hill prevented the other side from sun exposure. It was very pretty, although slightly reminiscent of ringworm. The hill's peak was gorgeous--a stunning view of the reservoir, some quaint houses along the shore, and plots of eucalyptus trees.

We had a delicious lunch (albeit a little late) at the Fazendinha, a more varied meal than what we've eaten here so far. I had a huge salad, some potatoes, some ambiguous fried vegetables, cous cous, and a little bit of pasta slathered in butter....I'm skipping dinner tonight. Oh, and I had a beer. Which was great. After stuffing our faces--we were all ravenous after our hike up the "mountain"--a few people hopped in the pool. Pas moi, non merci. Everyone was complaining about how cold it was, so I was not terribly enthusiastic about getting wet.

Of course, I got wet anyway: I rode in the smaller of the two boats on the way back to IPE and I was absolutely soaked through. Oh well. We had a good time and laughed while the spray drenched our hiking boots and backpacks, but everyone could see my ass through my wet pants when we walked back up the hill through the garden (where the produce that we eat here is grown).

I have a bit of homework tonight and I need to finish the reading from last night since I was occupied by my paper. The reading isn't too heavy, but we have a quiz tomorrow so I need to make sure that I understand all of the material. And I need to write a paragraph about my ideas for my project. I don't mind the work; at least I'm done with that paper. Thannnnnk God.
 
 
 

   
Paradise
This is paradise.

I arrived in Brazil yesterday, after a long flight with a four hour layover at JFK. My mum, being the lovely considerate woman that she is, ordered me a vegetarian meal for the plane. Unfortunately, the vegetarian meal also serves as the diet meal: not only did I miss out on the crackers and brownie, but my breakfast included a mini bagel while everyone else received one of more normal proportions. At least the flight was relatively smooth and the quintessential crying baby fell asleep soon after take-off.

My flight arrived in Sao Paulo at about 10am, but the SEE-U van was not scheduled to leave until 12:30, so I wandered around the airport for a while. I learned that women in Brazil (or at least in the Brazilian airport) are even more inept than American women when buying pants. Lots of muffin tops and bare ankles. Lots of whisker-wash too; I'm not sure which is more abhorrent. By 11:00 I was bored of aimlessly perusing souvenir shops and book stores full of trashy romance novels and maps in Portuguese, so I headed over to the Pizza Hut in terminal 2, the meeting place selected for our group.

There were a few girls waiting around a table; I identified them by the nearby pile of backpacks and suitcases. Oh, and the Columbia t-shirts. Everyone was very friendly and seemed interesting; we went through the standard introductions of what's your name, where are you from, what's your major, etc. Most of the participants hail from Columbia University (although I am the only Barnard student), but one attends NYU and another is from Delaware Valley College.

At 12:30 we loaded our luggage into a large van and drove for about an hour to our site. It was wonderful to step outside the airport after traveling for so long; palm trees planted on the roadside waved in a light, warm breeze, surprisingly warm since this is the Brazilian winter. The drive was beautiful, down a winding gravel road along the side of white cliff faces and through thick woods. Right after leaving GRU we passed through a residential area on the outskirts of Sao Paulo; the brightly painted concrete houses and dark-haired children sitting on the curbs reminded me of the neighborhoods of Belize City.

After driving for about an hour, we reached our destination: the Instituto de Pesquisas Ecologicas (IPE). The location is absolutely breathtaking--it's one of the most beautiful places I've ever seen. The center overlooks a deep blue reservoir; black and brown cows graze peacefully in the foreground, munching on green grass dotted with patches of wildflowers. There are some kayaks that we can rent and I would love to spend some time paddling across the water. The scenery also includes miles of tree-covered mountains stretching into the horizon. The Atlantic Forest isn't jungle-y like the Amazon, but it is amazingly lush.

We're all staying in a two-storey rectangular brick building with red shutters and external stairs; the rooms are small, containing two twin beds with only a few feet between them, but very comfortable. I was afraid we were going to be roughing it, but that's not the case. I think the mattresses may even be Tempur-pedic. (I slept very soundly last night.) There have been no hot showers as of yet, which is marginally disappointing, but it makes it easy to wake up in the morning. A brisk shower never hurt anyone and I'm sure it saves a lot of water overall.

The food has been excellent so far. For lunch yesterday we had green salad, rice, and a meat dish. I'd love to lose a few pounds while I'm here (what a great bonus). For breakfast this morning we had granola, yogurt (delicious!), crusty rolls, cheese, and lots of fruit. A great array of fruits--bananas, apples, oranges, mangoes, papayas, passion fruits, etc. All of the produce is grown in a nearby garden...I'd love to see it.

We had our first class after breakfast and went over some orientation topics: general safety and appropriate behavior, class schedules, grading criteria, etc. I'm really excited to start learning about this beautiful place; I think the educational material will be heavy but not too difficult, and I can't wait to spend time in the field. We each complete individual projects during our five week stay here, but I have no idea what topic I would like to study.

After class we went for a hike around the area, through a wide pasture, over several hills, and down a narrow path veiled by low hanging vines and thick shoots of bamboo. We saw some enormous spiders, lots of pretty flowers, and a sloth. Taking advantage of such a slow-moving organism, I took too many photos (as usual). When I upload them onto the computer I probably won't be able to decipher their subject, since the sloth was quite high up and my camera's zoom is less than ideal. He was very cute though and climbed down a bit to watch us as we watched him.

We have class again tonight until about 6:00. Afterwards, I'm hoping to finish the paper that I still have not turned in from the end of spring semester. I have about 20-pages so far and I just need to do some revision and add some more primary source references. It's by far the lowest quality writing that I've done all year, but I'm so burned out. At least it will be done soon and won't be hanging over my head. Hopefully Professor Rieder (who I hope to coerce into advising my thesis) will forgive me and won't judge my abilities too strongly based on this one assignment. He did tell me at one point during this semester that he thought I was brilliant. (I almost fainted.)
